    Sorry, but i could not understand.
    Please tell me how does Dumper return the string..

      Try it and see!

      my $string = Dumper {foo=>'bar'};

      From now on, always have a 'test.pl' file in your development directory. Whenever you're not sure, type in that file, and then Try It And See.

      It is like the Matrix, you should just try it and see for yourself...

[1nickt]: ++YourMother (Grammar Vigilante of Bristol)
[Lady_Aleena]: Um, how does grep do multiline? print "$file:$_" if grep { /get_(array|hash| data)\(.+\)/ } $_; only returns the same 18 lines the command line grep does.
[Lady_Aleena]: my scratchpad has what I have so far.
[choroba]: what do you mean by multiline?
[Discipulus]: thanks 1nickt!
[choroba]: grep is a filter, it selects elements from a list based on a boolean condition
[moritz]: you need to read the file in one go to do a multiline regex match
[erix]: ha ha, I like the Vigilante
[Lady_Aleena]: Forget it. I'm getting angry with it.
[Lady_Aleena]: I'll just have to search for the files using the subs and open them up.
